Receiver Status Screen Data
Operating and Programming Guide 3-15
Health and status indicators in the tables are defined as follows:
The health and status indicators in the Not Tracking table are
described as follows:
PRN indicates the pseudorandom noise code assigned to the
satellite.
El indicates the predicted elevation angle, from a range of 0
to 90
°
. The predicted elevation is derived from the
almanac.
- - indicates that the elevation angle is unknown (the
almanac did not provide this data).
Az indicates the predicted azimuth angle, from a range of 0
to 359
°
. The predicted azimuth angle is referenced to true
north, and is derived from the almanac.
- - - indicates that the azimuth angle is unknown (the
almanac did not provide this data).
C/N
(58503B)
or
SS
(59551A)
indicates the carrier-to-noise ratio of the received the
signal, from a range of 26 to 55. A ratio below 35 is a
weak signal that may not be acquired by the Receiver.
indicates the strength of the signal, from a range of 0 to
255. A signal strength of 20 to 30 is a weak signal that
may not be acquired by the Receiver.
Ignore indicates that the user has chosen to exclude this
satellite from a list of satellites available for tracking.
Not OK indicates GPS has reported that this satellite is
unhealthy.
Acq indicates the unit is attempting to acquire the satellite
signal.
Acq . indicates the unit is reading timing information from
the satellite.
Acq . . indicates the unit is reading satellite orbital
information.
ELEV MASK indicates the elevation mask angle in degrees. Satellites
at or above this elevation angle are considered for
tracking.
*attempting
to track
indicates that the Receiver is attempting to track a
satellite.
